To all whom it may concern:

Be it known that 1, JOHN H. GREEN, a citizen of the United States, residing at Springfield, in the county of Sangainon and State of Illinois, have invented ccrtainnew and useful Improvements in Renovators, of which the following is such a full, clear,'and exact description as will enable others skilled in the art to which it appertains to make and use my invention.

My invention relates to devices known as.

renovators and used. for extracting andromoving dirt by air suction from carpets, or other articles of furniture.

The purposes of my invention are to pro-' vide a renovator movable on the article to be cleaned and having an inlet opening in close proximity to the article being cleaned and rovided with means to prevent the article from obstructing the induction opening, to,

provide a handle of improved construction and means for connecting same Withthe body of the renovator so as to facilitate the introduction of the renovator into contracted spaces such as under stationary articles of furniture or the like; to provide means to enable the operator to observe the flow of dirt through the renovator and to rovide other details contributing to simplicity of construction and efi'ectiveness in operation. With these ends in view my invention consists in the novel features of construction and combinations of parts shown in the annexed drawings to which reference is hereby made,

andhereinafter particularly described and finally recited in the claims.

Referring to the drawings Figure 1. is a side elevation of the complete apparatus; Fig. 2. is an enlarged. to plan; Fig. 3. is a vertical section on the line 3. 3. of Fig. 2. F g. 4 is a vertical section on the line 4. 4 of Fig. 3 and Fig. 5 is an enlarged partial vertical section onthe line 5. 5 of Fig. 3.

Similar reference numerals designate like parts in the several views.

The shell 1. is referably of cast iron and has an internal 0 iamber 2. and a flattened and expanded forward part, having an inlet opening .3. occupying practically the full width of the expanded art of the shell; and a contracted rear part t e Walls of which converge to form an externally tapering tube 4. The end walls of the opening 3 are inclined as shown at 18 so as to make the slit or opening 3 effective along the entire width of the shell. The tube 4 is tapering in order that it may be connecting and disconnecting the hose.

forced into a hose 5. fitting on the tube, so as to inake'an air tight connection of the hose with the shell and also for convenience in tegral flanges 12. extend downward from the central part of the shell 1. Study screws 6 screw into'the sides of the bail 7 and extend through the flanges 12. and the roller 1]-.

turns on the studsof the screws 6. A curved handle 8 is suitably connected with the ball 7. The curvature of the handle is such that when it is de ressed the bail 7 will occupy an approximatey horizontal position close to the tube 4 so as not to interfere with introducing the head into restricted spaces such for example as the space under a book case;

and the upper part of the handle will be in convenient position for controlling the movement of the shell. A roller 9. referably of steel, is mounted on pins 10 and turns in the opening 3. The eriphery of the roller 9 preferably exteni s somewhat below the lower surface of the walls of the opening 3, as shown in Figs. 1, 3, and 4. One end of a hose 5 fits around the tapering tube 4 and its other end is connected to communicate with the vacuum chamber of any suitable vacuum producing device.

At the upper central part of the shell is an upwardly extending induction tube 13 communicating with the chamber 2. and the interior of the tube 4. A transparent dome 14 of glass or other suitable material having an integral annular flange 20 surrounds the tube 13 and is connected with the shell 1 by a screw ring 15 fitting on a screw threaded part 16 on the shell 1. Annular gaskets 17, of rubber or other yielding material, are situated above and below the flange 20. A follower-ring 19 is situated between the screw ring 15 and the upper gasket 17. The transparent dome on the renovator gives both the house-holder and the operator the same opportunity to observe the flow of the dirt and know whether or not the machine is operating effectively.

When the screw ring 15 is screwed down the follower 19 presses downward on the upper gasket so as to cause the gaskets 17 to make an air-tight joint around the flange 20.

In use the shell is supported on the rollers 9 and 11 and the user manipulates the handle 8 to move the machine forward. or backward or turn it in any desired direction. Apractically constant vacuum being maintained by the Vacuum'producing device not shownacting by suction through the hose 5, air

rushes through the inlet opening 3, and the chamber 2 into and through the induction tube 13, and the outlet tube 4, and thence outward through the hose 5, and in doin so produces suction which sucks the dirt rom the carpet or other article being cleaned and conveys it outward through the hose to the place of final disposition.

In ractice the vacuum producim device is preferably situated outside of the building in which the renovator is used. In cleaning carpets or the like the air suction lifts the fabric so that if means were not rovided to detach the fabric, it would comp etcly cover the inlet opening 3 and adhere to the underside of the flared part of the shell with such force as to materially impede the movement of the renovator. Forward or rearward movement of the renovator causes the roller to roll upon. the raised part of the fabric and the weight of the machine carried on the roller exerts downward pressure so as to continuously strip from the under side of the shell the carpet along the front edge of the inlet opening when the machine is pushed forward, and along the rear edge of the inlet opening when the machine is pulled rearward.

During the operation of the renovator the extracted dirt fiow's'through the dome 14 to the tube 13, and by observing this flow of the dirt the operator may be fully informed whether or not the renovator is operating satisfactorily and if the operation is not satisfactory may discover and remove the cause of such unsatisfactory operation. The dome 14 also enables the operator or other observer to determine when the carpet or other thing being operated on is cleaned and this saves loss of time by unnecessary use of renovator.

Prior to my invention the practice has'been to have a glass covered chamber apart from the renovator, the glass covered chamber remaining stationary while the renovator is in motion and the glass covered chamber serving to show the flow of the dirt after it leaves the renovator but not adapted to show the flow of the dirt actually within the renovator; the relation and connection of the parts being such that the renovator being in one part of an apartment and being in operation and relatively remote from the lass covered chamber in another part of t e same apartment, or in another apartment, it is impossible for both the house-holder and the operator at the same time to inspect it and observe the flow of the dirt through the renovator itself while the renovator is in operation, because if the operator were to leave the renovator to is in motion and in operation, said chamber being part of therenovator itself. I Having fully described my inventlon Whatl I claim as new and desire to secure by Letters\ Patent is:

1. In a renovator the combinatlon of a shell having an internal chamber, alsohavinga tubular part provided with an outlet opening and a flattened and expanded part rovided with an inlet opening extending a on the under side of said flattened and expande part, a roller occupying the'length of and mounted to turn in said inlet opening and extending below the under side of the expanded part of said shell, and a handle connected with and adapted to propel said shell.

2. In a renovator the combination of a shell having a chamber with a transparent wall, also having a tubular part provided with an outlet opening, and a flattened and expanded C{part provided with an inlet opening exten ing along the under side of said flattened and ex anded part, a roller occupying the length 0 and mounted to turn in said inlet 0 ening, and a handle connected with anda apted to propel said shell.

3. In a renovator the'combinationof a shell having a chamber, an inlet opening, an outlet opening, and downwardly extending flanges ierced by holes; a bail spanning the shelf and havin screw threaded holes matching the holes 1n said flanges, a handle connected with said bail, a roller fit-- ting between said flanges and having holes matching the holes in the flanges, and screws screwing into the holes in the bail and having pins fittlng loosely in the holes in the flanges and-the holes in the roller.

In Witness whereof I have hereunto subscribed my name at Springfield Illinois this 18th day of March 1905.
